CF 4.625″ to CF 3.375″ reducer

1 × CF 4.625″, 1 × CF 3.375″ (DN50CF) ConFlat flanges, 320.6 cm³ of internal volume and 233.2 cm² of wetted surface.

Build a system with this part

Its internal volume and surface area feed the pumpdown simulation, and its 3D characterization sets how it affects pumping speed.
